WIRE MATTRESS FABRIC.

Specification of Letters Patent.

Patented oct. 25, 1921.

Application filed October 26, 1920. Serial No. 419,769.

T 0 all whom it may concern.

Be it known that I, JAcoB LIBow, formerly a subject of the Czar of Russia, but having resided in the United States of America for about sixteen years and having declared my intention of becoming a citizen of the United States, now residing at Springfield, in the county of Hampden and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Wire Mattress Fabrics, of which the following is a specification.

This invention relates to improvements in wire mattress fabrics of the type in which a series of links are connected together to form the complete fabric or bed-bottom.

An object of the invention is to provide a mat-tress fabric that is simple in construction, one in which the individual links can be readily formed and then locked or connected together to form the finished bed-bottom, and one that is practically non-stretchable, by placing the connecting links or loops in direct line with each other, longitudinally of the bed-frame.

A further object is to provide a fabric that possesses uniform tension over its whole surface.

Referring to the drawings:

Figure 1 is a bot-tom plan View of one form of fabric in which the links have portions that cross each other in the finished fabric, and showing offset or loop portions therein for connecting the links together.

Fig. 2 is another inverted or bottom plan view of a modification'in which the links are practically double-U-shape in form, and having their intermediate integral connecting portions of the same length as the side portions; also showing the links assembled into the complete mattress or fabric.

Fig. 3 is a further modification in which the units or links are formed in one continuous piece.

Fig. 7 is a modification of a fabric in which the links shown in Figs. 5 and 6 are combined and alternately located.

Fig. 8 is a sectional view on the line 88 of F ig. 2 inverted. I

Fig. 9 is a top plan view of Fig. 8.

Referring to the drawings in detail: The individual links shown in Fig. 1 are made up of the crossed portions 1 and 2, and the loops 3 and 1 at their outer ends. The portionsare connected together by the integral portion 5 having the offsets or loops 6 and 7 at its ends, asshown.

In assembling these links in the manner shown in Fig. 1, the edge wire 8 is used to form the opposite side edges of the finished fabric. The wire is integral with the part 9 and having its end 10 connected to the loop portion 7 of the link. This edge wire forms a strong non-stretchable edge to the finished mattress. The bend 11 passes through the eye 12 of the link in row C and through the loop 13 of the wire 8. The outer end of the side wire 8 is formed with a loop 14 which is connected to the outermost helical spring 15 which in turn is connected to the end rail 16. Also attached to the spring 15 is the crossed portion 2 of one of the links. The other crossed portion 1 of the link is attached to the adjacent helical spring 17. Attached to the spring 18 is the portion 1 of the adj acent laterally disposed link, and having its loop 6 arranged at the right of the loop 6 of the first row A of links; the intermediate portion 5 extending between theloops 6 and'6, and the portion 2 is connected. to the spring 17. The links are arranged in rows extending laterally and longitudinally of the bed-frame, as indicated at A, B, and C. The row of links indicated at B is arranged in the same longitudinal and transverse lines as those in row A. In this row the crossed portions 19 and 20, as shown in Fig. 1, are at their outer ends passed through the eyes 21, which are formed bythe loop or offset portions 6 and 7 and placed in overlapping relation so that the portions5 and 5 extend across the bed. The links of row B are assembled like row A and are attached to the links in row A as described. The same description would relate to the links in the next row indicated at C. The edge wire, 8 may, if desired, we tend only from one link to the other. The finished fabric, therefore, presents an appearance in which portions of the links cross each other so that the general appearance is that of a fabric having diamond and triangular shaped openings.

Referring to Fig. 2, in which the individual units of the link are composed of the members 22, 23, 24, 25, 26, 27, which form substantially a double U-shaped link or unit,

the parts 24 and 25 form intermediate loop portions which are of the same length as the side members or portions 22 and 27. The portions 23 and 26 have the offsets 28, 29, 30, and 31. The units of the row E are united to the units of the row D by passing the loop portion 32 of the members 24and 25 over and locating them in the offset portions 29 and 30, while the ends of the unit engage in the offsets 28 and 31 respectively. The samearrangement is carried out in the row indicated at F, with the result that the portions 24 and 25 of each row are in alinement with each other and extend lengthwise of the fabric as indicated by the dotted line 33-34 in Fig. 2. This prevents the fabric from materially stretching lengthwise. Also, the loop 32 pinches the portions 24 and 25 together laterally. Attached to the uppermost row of units and to the bed frame, are the helical springs 35" to which the loop part 32 and the side portions 22 and 27- are connected alternately.

The individual links or units in this form of fabric, may be termed a double U-shaped link that is connected together by the members 24 and 25. The generalappearance of the fabric is of openings that are substantially rectangular in form. In this finished fabric there is no possibility of the finished surface sagging or contracting laterally.

In Fig. 3 the rows G and H are. made up ofunits all of the members of which are continuous and have integral connections, indicated by the numerals 35, 36, 37, 38, 39, 40, 41, etc. The loop members 37, 38, 40, and 41, areattached to the loops 37, 38, 40, and 41, of the row G in the same manner as already described in connection with the loops 24 and 25 of Fig. 2, and the end loops 42 of row G are connected to the row of springs 43. The end portions of the units of row G are connected to the outermost springs 43, as shown. In this construction the line extending lengthwise of the bed from one end spring to another, receives the load and prevents the fabric from stretching longitudinally, as described in connection with Fig. 2. There can be no lateral displacement, as the members 37 and 38, etc., are held nearly together. Individual units cannot shift laterally as the loops 42 which are located in the offsets in the connecting parts 36 and 39 will prevent any displace ment.

Referring to Fig.4, in which the construction is substantially the s me a th t ShQ l in Fig. 3, the individual members of the loop portions 44 and 45, instead of being open as shown inFig. 3, cross each other, as shown at 46. The connecting loops 48 of the members 44 and 45 of the outer row I, are attached to the helical springs 49. The units in the row J are connected to the units in the row I by passing the loops 48 over the crossed portions 44 and 45, as shown. These are located in the offsets 50 of each of the units. The load is carried in the same line, as described in connection with Figs. 2 and 3, whereby the fabric is prevented from stretching or sagging, and will maintain its original shape. The units of each of'the rows cannot move laterally, as the loop part 48 rests in the offsets 50 and normally pinches the portions 44 and 45 together.

ig. 7 shows a fabric composed or made up alternately of the links or units shown in Figs. 5 and 2. In assembling this form of'mattress the double U-shaped units shown in Fig. 6 are arrangedlongitudinally of the bed-frame, then a longitudinal row of the crossed links shown in Fig. 5 is connected, then another row of the double U- shaped links, and then another row of the crossed links, andso on, until the fabric is complete. The crossed portions 1 and 2 are shown connected tothe offsets 28 and 31 by the ofisets 6 and 7 of the crossed units. This construction prevents the fabric from sagging, by reason of the connecting points of the links being arranged in longitudinal alinement or arrangement, as already described in connection with Figs. 2, 3, and 4. The mattress will maintain its shape over the whole surface without sagging, as the transversely arranged portions of the units are so interlocked together to prevent such movement.

It will be seen from this description that all of the different link formations disclose a unit or link in which laterally arranged sidemembers or portions are employed, and intermediate en'dportions having offsets in which are located or attached the links of each of the rows of units, both laterally and longitudinally of the bed-frame.

It should be observed that the mattress fabric shown in. Figs. 1, 2, 3, 4, and 7 illustratesthe bottom. side of the fabric instead of the top surface. The detail view shown in Fig. 8 illustrates the idea thatthe bend 32of the loop portions 24 and 25 is slightly downward, thus producing an upper smooth surface of the fabric and prevents wear on a mattress whenplaced thereon. V

It should be noticed from the construction shown in Fig. 2 that the links 24 and 25 beinglocked together will receive the I strain and prevent the links 22 and 27 from opening or drawing apart where'they are connected to the loops or offsets3l, In making the spring bed there is no danger of the links 22 and 27 openings, as the links 24. and 25 receive the load. There is therefore no danger of the fabric as a whole becoming narrower or out of shape. By arranging the closed links 24 and 25 alternately with the links 22 and 27, the shape of the fabric as a whole is maintained.

It is obvious that the links 24 and 25 in Figs. 2 and 7 at their inner or open ends may be connected together at the other end of the bed-frame by means of rings, and also connected to the helical springs. The same thing is true of the links 37 and 38 in Fig. 3, and of the links 44 and 4 5 in Fig. 4:.

It will be observed that a portion of the fabric shown in Fig. 7 has crossed portions that are substantially X-shaped alternating with the double U-shaped units.

What I claim is:

1. A wire bed-mattress fabric having units which are formed with lengthwise extending side members and end portions integrally connected to the side members and having offset at the points or bends which connect the side and end portions together, said end portions having intermediately located and lengthwise extending loop portions with only a single bend or turn therein at the ends or the intermediate part of the loops, said bends or turns engaging the offset portions of the adjacent rows of links to form a fabric in which the weight borne by the fabric will be distributed lengthwise of the same and through the connected loop portions, as described.

2. A wire mattress fabric comprising a plurality of rows of individual units arranged laterally of the completed mattress and each unit having a series of lengthwise extending loop portions with only a single bend or turn at it intermediate portion and having offsets at their bases, each row of units having its looped portions connected to the offsets of the looped portions of another and adjacent row of units in straight longitudinal lines, whereby the weight will be distributed longitudinally of the fabric and in line with said loops.

3. A wire fabric comprising a plurality of individual unit members having offsets therein, and portions extending from the offsets and formed with hooks at their ends, looped portions intermediate said portions and having only a single bend at their intermediate portions, said hooks and looped portions serving to connect the unit members together, the line of connection being in substantially straight lines from end to end of the fabric to prevent sagging.

4. A mattress fabric comprising a plurality of substantially U-shaped integral units having intermediately located looped portions therein and offset portions at the base of the looped portions, the ends or bent part of the looped portions of one unit being connected to the base part of the looped portions of the adjacent rows of units and in the offsets thereof for arranging the looped portions in longitudinal alinement with relation to each other to prevent longitudinal sagging of the fabric, the end units being adapted to be connected to the end rails of the bed frame.

5. A wire mattress fabric formed by uniting two series of units, one of the series of units comprising members each of which is formed in substantially a double U-shaped form, and the other series of units comprising members each of which is formed in substantially X-shape, said series being alternately arranged in rows longitudinally of the mattress, as described.
